The lubricant system in a centrifugal compressor is unique in that at no time does the lubricant come in contact with the air path. Instead, the lubricant serves as a high-speed hydrodynamic gear lubricant. Being a straightforward system, many operators choose a standard hydrocarbon-based rather than a lubricant formulated for the specific conditions a centrifugal compressor operates under such as high-speed rotation and heat.
